Letters Patent No. 108,253, dated October 11, 1870.

IMPROVEMENT IN TRUSSES.

The Schedule referred to in these Letters Patent and making part of thesame.

l .Tous Goeman, of Philadelphia, county of Philadelphia, State ofPennsylvania, have invented an Improved Truss and Truss-Pad for Hernia,dre., ol which the following is a specification.

Nature and Object of thc Invention..

My invention consists of a truss provided with a lever and a projectingnut, which turns on an cecentricpin, so that a lateral adjustment of thenut may be obtained by merely turning the saine.

My invention fnrthur consists of the combination of the said lever, itsnut, and adjustable shield, as fully described hereafter.

Description of the Accompanying Drawing.

Figure 1 is an edge view of my improved truss. Figure 2, a iront view ofthe sani General Description.

lhe truss consists of what l have termed an abdominal lever, A, and of ashield, B, and projection or uut C, secured to one. end of lthe saidlever. i'

The abdominal lever consists of upper and lower plates d and dl,suitablyl curved and connected together by a bent or curved neck di.

'lhe upper plate is adapted to the shape of the lower part of theabdomen, and is intended to fit comfortably agaii'ist the same with aslight degree oi' pressure.

This plate, for the sake of lightness, and for the admission of air, maybe perforated with a number of holes, e, as shown.

The lower plate lll of the lever, which l have termed the orifice-plate,is intended to cover the groin or inguinal region, the seat of thehernia or rupture.

This plate is nearly dat, and has secured to its inner face theeccentrically-adjustable nut C and shield or guard B, before referredto.

At the back of the plate lthere should be a projectii'ig screw orbutton, for the attachment of a spring and strap, to secure the lever tothe wearers body.

.lhe projection or orilice-nnt G is intended to enter the oi'iiicc orlower ring of the inguinal canal, in oi'- der to press back the hernia,and may resemble, in shape, the end of the thumb, or be made round,oval, or other suitable form.

It is secured to the plate (il of the lever by a screw, j, in such ainannei that it can be adjusted eccentrirally upon the same, or it maybe secured by means of an eccentric stein at its inner end, adapted to asocket formed in the plate.

The guard or shield VB is also secured to the plate ft' by one or morescrews, in such a manner that it may be readily adjusted thereon, and ismade of the peculiai' curved or scmicireular shape, best observed infig. 2, in order that it may partially surround the orice-nut, and, bybearing against the parts ofthe body beneath the orifice, and on theside toward the hip, regulate the pressure ofthe said nut upon thehernia.

The raised portion of the shield immediat-ely sur rounding theorifice-nut consists of a ridge somewhat liigher than the nut at x, andtapering inward from this latter point toward the plate dl, the saidridge being so reduced in height at its upper end :is to meet the plate,while, at its lower cnd, it terminates abruptly in a point, ai', a shortdistance outward from the plate. (See iig. 1.

The inner edge ,i/ of the shield, which surrounds the orifice-nutisnearly vertical, and the portion y ofthe said shield is beveled, orgradually rounded off to a thin edge, so as to fit comfort-ably againstthe parts with which it is brought iii contact.

The above-described truss, when adapted to the body ofthe wearer, isheld in a'proper position by the spring and strap before referred to,the springr passing half way round the body, and pressing both theorifice-nut and the shield equally upon the hernia.

As the abdominal lever A, which forms the body of the truss, isadjustable upon the spring, and as the critico-uut and shield are bothadjustable upon the lever, it will bc evident that all of these partscan be set at any desired angle, and in any position, to suit thepatient, and nature ofthe rupture.

The lever A acts as such, iii case of sneezing, coughing, 8:0., theplate (l being, in such case, forced outward with the protrusion oftheabdomen, and

forcing the plate lll, whicl1.forins the short arin of the lever,inward, in opposition to the elort of the hernia to protrude by such actof sneezing or coughing, the lever turning upon the spring, to which itis attached, as a fulcruni.

The-lever A should be made of'such a shape as not to press severely uponthe abdomen in the act of steopin fr.

It should also be made flatter upon its inner than on its outer edge, asshown in fig. 2, so that when two of thctrusses, or a truss and a pad,are used, one upon each side, they may not strike together, or otherwiseinterfere with cach other.

' It will be observed that the oricennt and shield Claims.

1. The pressure-pad or 1everA, provided with a supplemental pad orprojection, turning on a. pin arranged eccentric to the point of theprojection, as described. e

2.-The combination, substantially as herein described, with the leverand its adjustable nutl C, of' a shield, B, adjustable laterally on saidlever, in the manner described.`

In testimony whereof, I have signed my nume to thsspecification in thepresence of two subscribing witnesses.
